Ha...Jews and anyone who opposed him. I have non-Jew relatives who did time in concentration camps. One for being an avid Catholic church supporter. The Nazis dismantled their family estate brick-by-brick and then locked them all up. Another seems to have predicted a future defeat and subsequent hard times, and was locked up for that. He escaped, made his way to America, and became a fighter pilot in WWII over the Pacific for the US Navy.
